I have a 400ex on the rear with a 4" ext swingarm and worx on the fron with +3+1 asr arms. Love the combination.

So I am considering a yz250 swap . would you do it again? Is the hp there over a bored and stroked 240bbk? what is the power of late 80's yz250?

Is the blaster cdi rev limited. If so what is the limit.What are the options?

Thanks, I just need to get my butt in gear!!

So I am about ready to go oversize with my ported 240 cyl. Pretty good rattle in it. I will probably send it to Denny as he did my head to run on race fuel. Have a +3 crank in the box rdy to go. Vast improvement or not? I can redo the port timing to the longer stroke. I am running a 34 PK and...

Flushed it as soon as I got home. Oil was clean. The whole day turned out to be a dumb a#s attack. Motor is back together tonight and sounds healthy no excessive noise. I am going to tear into my intake and make sure I have no leaks in the carb to filter adapter. I have been using grease under...

It turns over very quiet but of course there is really no telling how the bearings look. I did not hydro lock the motor but it did lay down from water injestion. It fired right up and I ran it for another hour since. BUT it is getting noisier. I have a new +3 crank and bearings but I am hoping...

I have Razrs and they dont seem to work anywhere but on a track. If you are considering something that will work all around I would see what others say about Bandits. I know a couple of guys are racing with them? Any comments. We ride in all kinds of terrain in Florida lotsa sand and loose mud.

Yeh, I pulled it apart and the piston is scuffed. Got a new one today. The cylinder cleaned up ok. I think I am getting dirt somehow in the intake> I need to disassemble the boot and adapter and make sure they are clean. It probably did not help that I dipped it in 3' of water and killed it...

Turns out the piston is scuffed on the exhaust side. Cylinder looks good. .. I was riding in a lot of dust. Either dirt is getting by my UNI filter OR it got too hot. The skirt is scuffing. The bore cleaned up nice. I will check clearance after the new piston gets here.

As for the noise I build outboard drag motors and it sounds like just a wrist pin. I may have to put in my new +3 crank if it is coming down. As far as running upside down. I couldn't believe it would not shut off. AND I have a perfect one inch hole in my butt where the darn handlebar pinned me...

Rode 6 hours today and picked up a noise in the top end after a serious flip. Bike ran for 5 min upside down before I could get out from under it and shut it off. I am hoping it is a wrist pin brg. Sounds like a small knock. Vitos 240 kit w/ approx 15 hours on it. Ported on race gas. Klots R50 -...

My big bore CPI is all over the Toomey I ran before!! Night and day mid to top end.

I run 15/40 with 18" tires. I ran the chain around once to see where it was close and cut a very small groove in the case. Doesnt touch, been running it like that for a few months now. It looks like it will touch but actually clears when you bolt up the retainer. The plastic on the other hand...

Thanks. I will do just that!!
