Usually about 2.5k-2.8k, but little less then 2k since I've had Tom build a couple motors and mine was already at the right bore. It includes engine build, blueprint of stroker, machining and mod case for stroker, decomp valve in head, porting, head ... more »

For sure not bolt on. But really need to modify the crankcase (too little volume) to get good power out of big bore. Tom noted about 48hp with esr and 58hp on Dyno with TMR 315, smoother and better partial throttle torque. And being plated is nice. That's ... more »

I know someone has PW50 for cheap, might try to snag it eventually. Desert tank will be used for dunes and some of the longer rides.

Pretty easy to make these bikes from stock so-so to great. I took a stock beat up 2006 and went full TMR 295cc. Now being built by Tom Morgan for 315cc stroker, and suspension done by Enzo. No idea if Vforce made any difference since I went from worn ... more »

50:1 Redline, Tom Morgan recommended on my build. Only ran 32:1 petrol based for break in. As long as you run good quality oil (I prefer synthetic), correctly jet, good gas, and clean air you will be good.

I wasn't able to pick the bike up, was a day late!

The position is still TDB, I'm sure they will get back to you on it as ASAP as possible.

Did you notice bottom to top end over rev difference from PC shorty to any of the long silencers? And what did you modify on PC shorty?

How do you like the DEP silencer vs the Pro Circuit silencer? Haven't seen many reviews for DEP's silencer. I have R304 now and thinking of doing same DEP as you since I have the pipe.

Maybe not directly related to parts/gear but GoPro Hero 7 Black is $316. Say's expired but I just ordered for $316 shipped. https://slickdeals.net/f/12315898-google-express-black-friday-20-off-coupon-gopro-hero7-black-for-316-coupon-works-on-limited-other-items?src=SiteSearch ... more »

Ordering the FMF Powercore 2 to test out. Tom Morgan said it will work best (with 315cc big bore/stroker) so will try to do comparison with R304 silencer and DEP pipe. I've seen a few people mention they like DEP and 304 long the best. Has anyone also ... more »

That's kind of what I was thinking on RM85 parts. Tried contacting evo-mx for the tank graphics but they don't make anything for 80's. I haven't seen the bike yet, just trying to see if it's worth it still.

Added reply in a thread YZ250 Stock Pipe with PC R304 Combo 11/21/2018 7:52 AM

Regarding the R304 and 304, is the exhaust opening smaller on the R304? It seems it is but never really looked in person and I don't have the 304 (long silencer)

Added reply in a thread 1991 RM80 11/20/2018 5:55 PM

I think I'm going to go for it tomorrow. Trying to decide what to do. Restore to stock with warning stickers, etc...or full on works mini racer from that era. Pretty 50/50 on it.
