Need veteran advice on exhaust

[Wait4me]

Hey everyone, my Xmas present is a new pipe/silencer for the TBlazer 250. I have narrowed it to 3 choices and each claims to be the best thing for my quad, so I have no idea which is the best choice. I need some advice from the vets out there so I don't waste a good chunk of cash.

Here's what I am looking at:
DG "Extreme" pipe with either steel round silencer or oval silencer

HotSeat Perf. pipe and silencer combo

Hi-Perf.Designs black pipe with MTD silencer

They are all relatively the same investment so cost isn't influencing my choice. I did have a HSP clutch kit put in at the dealership with an aftermarket air filter. The mechanic said it is jetted for an aftermarket pipe right now so I can install it when I bought one. I am looking for an exhaust that will help my acceleration more than top end also.

Thanks in advance for any and all help. See you all soon. Take care.

How's the tires? Personally, If it has the stock tires on it, I'd put on some different ones. But if you want better acceleration, I guess a pipe would do it since you already have the clutch kit installed. OR...jet it to what it's suppose to be jetted at stock w/ just a filter and it will probably accelerate better than it does now. (meaning.. you jet it for what mods you have currently... you dont jet on wishful thinking for future mods)

Keep in mind you are only going to get so much out of that 250. Of the companies you mentioned I would look into the hotseat pipe or I would actually do some research on this this company.

If you are looking for max acceleration out of this thing you could drop a tooth or two on the front sprocket too.

In 2-stroke tech the pipe design is the major influence on where the powerband starts its dramatic up sweep on a dyno chart. A top end pipe expansion chamber (large mid-section) will be very large towards the end of the pipe to where it connects to the silencer. A low end pipe or one that starts that hp sooner in the rpm range will have a longer symetrical design to the expansion chamber.

I would be careful about this guy saying its already jetted for a pipe. Is your bike still oil injected or do you pre-mix. The jetting on a two stroke does two things. It primarily lets in more fuel to cool the piston and lubricate things. So I don't have to type a book here pick a pipe and we can give you advice on tuning it. Just don't sink a ton of cash into a bike that will only take ya so far.

Go buy the Bill Ballance edition YFZ at Brenny's!!!!!!!!!!!

Ubnpast, yep I still have the stock tires on it and did hear that putting smaller dia. holeshots would help the take-off....and maybe I'll get them as my next big investment. I have been reading the factory mechanics manual on my quad and it has so much info, I am overwhelmed....but I kinda understand the jetting and your advice makes alot of sense. I know all the extra parts will only help with everything being tuned together so I would gladly pay someone to stop by my shop and get my ride dialed in once I get the pipe in.

Weck, I thought there would be alot to consider before picking a pipe and I appreciate your patience with my questions. I DO still use the oil injector even though people tell me horror stories about "a guy I knew". I did like the Hotseat pipe but it looked like a 1 piece outfit and I didn't know if it was better to get a silencer that can be replaced without getting another pipe too. It may be 2 pieces, just pictured all together. Since I already have the HSP clutch, I better stick with that brand for the pipe too.....as probably works better than 2 different brands. I'll get it ordered in a day or two and beg for help when it comes in. My shop is right outside Coal Valley, IL so when I get it I'll post it and ask for somebody to help tune it all together......for cash money!

I know I am only going to get so much out of the lil 250, but with my inability to show self-control on motorized toys......I have learned to either buy small to limit the machine's ability, don't buy anything to limit my ability, or die. My very first "crotch-rocket" drive netted me 116 mph and a pissed owner. I can't help myself. 250cc is my friend. I have 3 little ones now, and they need DAD!!!!

Almost forgot.....is it possible to wheelie a Tblazer with it's auto tranny and combo brakes? I know some people can wheelie anything (Ubnpast??) but without being able to keep it in a partcular gear, is it too hard to learn on an auto? I learned how to wheelie a wheelchair in 20 minutes so I have great balance! (and I keep the wheelchair around just in case) Just wonderin' Take care.

HAHA, thanks for the compliment. Although I haven't tried to wheelie an auto tranny such as your trailblazer, give me 2 minutes and I'll tell you how hard or easy it may be. The clutch kit might just help with that. I would have to assume that it would be harder to hold it in the balance point because of the lag in the clutch mechanism. But that's just this guy's opinion.

[Weck]

I have seen a lot of utility quads wheelie with sheer power so I suppose its possible.

I would stop by to help with the quad but I only take cold beer as payment. That explains my very short warrenties. ;D

[Wait4me]

Maybe at the Keithsburg ride, UBNPAST will give the TBlazer a go at pullin a wheelie and let me know if it too hard to learn on. If sheer power makes an auto trans. wheelie easier, then the Sportsman 600 should be able to pull it easier than mine. The 600's weight is too spooky for me though, so if the TBlazer is difficult...then only wheelchair wheelies for me.

Weck, if you really can help me when I have all the parts in....I would gladly have a stocked cooler next to the tools!! What would be your flavor of choice? I love the new Leinie's Sunset Wheat myself. Would a couple "drinks" for the road buy me an extended warranty?! ;D ;D Take care.

3 simple things:

1. I want to be present for the wheelie class

2. Bud Select

3. Warrenty is up when I pull out of the drive way.

See you at Keithsburg or Southpark mall parking lot at 8:00AM

[Wait4me]

3 complex answers:

1. If UBNPAST is willing to spend the time trying out the TBlazer and possibly giving some pointers, I am sure he doesn't mind the additional spectators. IF the quad is able to do a decent wheelie, I am under NO OBLIGATION to repeat the feat!!! The health of the quad and it's rider will always be my primary concern. Also, judging by Xman's avatar....he can pull up the front with the best of 'em so a second opinion may be in order. (UBN's comfort with wheelies may impair his judgement when determining if a newbie rider like myself could do it) Then again.....Xman is pulling it up after whipping a 540, so he may be alittle too good too. Aw heck, let's just see what happens at Keithsburg.

2. DONE!!

3. Sounds fair enough, as I can always keep bugging you on this darn website! hahaha

I will be at Southpark on Sat., so I can follow everybody there.....remember, I don't know jack...including directions!! Thanks again Weck. Take care.

[mojaveleclaire]

i will give it a shot as well in pulling a wheellie. i think ubnpast and myself will get along great with our wheelie contests, espically on someone elses!! if my buddy shows up for the ride saturday he will enjoy the wheelie contest as well. i could be just as happy in my yard doing wheelies all day long..

I for one know you could use the class! A wheelie isn't a wheelie if it's under 6 feet in length.

[Weck]

I did 10 feet one time then got scared and stomped on the brake...hahaha

I also rode a wheelie on a Quadzilla about 60 feet then crashed into the back of my Dodge, you would have loved to seen that.

Well if we are practicing wheelies at least the sand will give a little softer landing for the backside.

[rrwilley]

Gosh: Theres a lot of good advice out there, But I would really like to Talk to your mechanic. Anyways Not to critasize anyone here it goes!

Weck is correct, The pipe isn't as important as the expansion chamber.
UBN passed is correct, Jetting for wishfull thinking isn,t good.
Tire would help.

But the most important think to remember is to drasticly change the performance of a 2 stroke there are three things that need to be changed!

1. Air filter, already done.
2. Pipe/expansion chamber, Working on it.
3. Reed valves?? I understand that most people never consider the valves on a two stoke. Boysen is a name brand that is, well was anyway with the two-stroke crowd.

Hope I didn't confuse you more.

[ubnpast]

Yeah some Boyesen reeds would increase throttle response. You will notice the power hits a little quicker than stock. And it's fairly inexpensive when putting it up against the other mods you've done.

Also a reed spacer will increase the amount of air/fuel mixture in the combustion chamber resulting in more low end.
