90 Pipe recommendation?

[dwhst9]

Our Scrammy 90 has a bone-stock motor for now. This will primarily be trail ridden, but I want to be able to reuse the new pipe with future engine mods. However, I don't want him to have a wicked high engagement right now. Will the Hetrick pipe still meet my needs or should I look elsewhere?

Went down the same way with my sons 90 preddie only i got my pipe from Lakes motorsport its called producktion pipe but i think its the same pipe.To use this pipe you need a high rev cdi and a uni filter and rejet your carb,this shold come with the pipe.Ended up changing the carb to a 21mm dellortho with stock jets,this made it go really fast on straigth rugged terrain and on the track even without the cluch kit:devil:

guy has a Hetrick Pipe/Trinity Pipe for sale in the Polaris section.

check it out

the metrakit pro pipe will have the best allaround performance and works well with mild mods. very good low end performance

Are you running Hetrick pipes with stock motors and mild engagement?

[Nocomment]

when we had it on the bike it was with lightend clutches and springs, and rejetted carb other than that stock,

Either way for a 100 skinnies grab it. I have a new lightened clutch when your ready for it.

I told Tom I'd take the Hetrick pipe. Where is weight removed from in that clutch? Are you referring to less rotating mass?

[03sp500]

by drilling out / lightening the clutch shoes, you change when they engage. the lighter shoe engages later so the engine can get up to the power band. then you get to play with rollers. torsion springs, ramp angles, variator spacing, belt length, overdrive pulleys, it just never stops. setting up a clutch is a black art.

but it is real neat when they hook up and pull. trust me it never stops.

Boy you said a mouth full there........ I'm liking this Honda clean the air filter, change the oil, check it over for loose, bent, broken, or cracked stuff........ if it's all good load it up and lets go racing.

I understand all the clutching stuff coming from a stable of Polaris quads. I just wasn't sure if Mike was referring to lightened clutch weights or the entire clutch assembly itself was lightened too.

. If you are trail riding and want to keep a low rpm clutch engagement, I dont think you will be happy with the hetrick pipe , it works better for high engagement and full throttle racing applications. If you decide to get it then plan on changing clutch , t-spring , rollers and jetting and sprockets to make it managable in the trails .
good luck
