Converting to a 2 stroke

Im a 4 stroke guy, but i respect and like banshees to

I've got an honest, no bullshit question... How do you keep a timing chain in that thing? Is there a brand I don't know about? The 2 MX bikes I sponsor/build go through one (chain) a season (12 races roughly and the practices) That is one of the reasons for my 'reliability' stab earlier..... The other is piston life, the YFZ below goes through a piston a season and the Suzuki one every 2 seasons. (The piston life is acceptable considering the duty cycle)

 

I've tried several after markets, and have resorted to OEM.. One bike is a SUZ450 and the other YFZ450 quad. SUZ is stock except for my porting and a custom ground cam (not very aggressive lift) The YFZ is my porting, 3 mil and CP piston, and web intake cam. Dynos a broad torqued 69 HP for the YFZ. They both kick ass on the track and the SUZ was 1st last season and the YFZ was 2nd-both 2nd year racers.....

And they sound funny.

For racing

Mx on them it sounds normal. We have changed the timing chain once since the build.

Not patting myself on the back but my raptor comes out harder then most. Its not every raptor holeshotting like that. Good chassis, tire, gear combos along with hp/trq

4 stroke power vs. 2 stroke power is a lot different. I outrun 2 strokes showing 30+ more hp on a dyno.

[JLO298]

And your right for a good drag race head is more than $1500

That guy on the rappy is me lol

4 strokes also hook better in general. There was a big discussion on atvdragracers. Banshees spin off the line way more in general.

Thanks JLO.... Just didn't know if there was something (chain) lurking around out there I didn't know about.

 

I agree with the posts above about Dyno numbers.... They are a tuning tool not a race performance predictor. We have a dyno in the shop here, and I hold local Dyno shoot-outs with it too. Amazes me the credibility people put into these things 200 HP put to the ground incorrectly can be totally shamed by 50 HP set-up right, in a race!!!! JLO not only makes power, but puts it down too

JLO's wife looks better than his bike. Just saying.

 

 

 

[JLO298]

I love them both equally lol

Bet your wife gives a mean foot rub tyler
