General Two Stroke Talk / Had a little epiphany at the track today.....

« on: August 15, 2013, 03:11:55 AM »

Don't know but just wondering if the rear wheel being farther back (assuming you didn't shorten yout chain ) has an effect in the handling?  I think with the wheel back farther you can get more drive and the bike is less prone to wheelie. I know it really helps in the single track I ride with some of the steeper hills.

Rear wheel is forward. I put a new chain on at the same time. It was short. The axle is almost all the way forward. I have found over the years that I like the rear axle forward. It seems to improve my turning  and I like the feel. I think it's an individual thing.

I was doing some bike maintenance and needed a new rear sprocket. I found a few on the shelf in the shed I got from RMMC on sale last year. The down side was that they are 47's and I've been running the stock 50's on my rm. I threw one on just because I'm not racing lately and wasn't concerned about all out acceleration.
At the track this morning I was surprised at how well it hooked up! Acceleration like a beefy 250f. I could hold a gear longer and twist the throttle harder without any loss of control. And the suspension felt more forgiving over accel bumps coming out of turns. I found myself launching further over jumps too. I had been concerned about a loss of torque but I actually felt more due to the increased grip.
I have a very fast buddy, rides and often wins the expert vet classes, that regularly runs -3 teeth in the rear and for gp's will even go up one tooth in the front on his yz250. I had been a doubter of his setup, but now .....?
I probably won't go to his extreme gearing, but I'm gonna stick with the -3 on the rear, at least for the 3 RMA sprockets I have left..

HHHmmmm, I think I know what it is, but you'll have to send it to me to be sure. I'll let you know how it works out....



sorry, just joking. Check your airbox seals and carb to boot alignment.

Technical / Just some wild musing......

I came across a ktm adventure bike. The big, 950 type, with a blown motor. The owner says it would be big bucks to repair or replace.
I'm just remembering the fmf / ktm / kx500 thread, and wondering if a kx500 motor could be mounted into the bike frame, and would it be worth the work and $$$$?
A 2t adventure bike , lighter than oem, ? less torque for sure. Enough power?
Any ideas on another 2t motor ?
Thoughts? Comments? Opinions?

that is the throttle position sensor. I've never messed with mine. Break out your manual and put it on correctly.....
Good job on the cleaning.
In the picture of the right side of the motor, the powervalve actuator, is that round disc piece on backwards? It looks like the backside is facing out? If I remember right, mine has two cutouts on it?

Technical / Vibration and flywheel freeplay - rm250

« on: February 25, 2013, 03:32:20 AM »

I took my frame to a welder buddy to get the broken motor mount fixed. We were looking at the bare frame and welds. Has anyone noticed how rough the welds are? They look almost frankenstein. I was thinking that the frame may have been previously repaired but my buddy pointed out other welds all over the bike that were rough. And the amount of slag painted over was surprising too. Is this common with suzuki?

Beaner did you into any problems with the bedliner spray? Did you have to plug the holes or did the shop? How much $$ ?
How did it turn out? Was it sprayed everywhere?






..... and yes, laveneder would be my "go to" choice......

I'm looking for opinions on what color to go with.  After having to rebuild my bottom end on the 05 rm250, I found a broken front engine mount. I'm getting it repaired tomorrow. I figure after having to strip down the frame for the other repairs I might as well get it powdercoated. I'm looking for ideas as to which color to go with? OEM? black? I'm not into yellow frames... Has anyone seen any other color used on a suzuki?
I want to get it done this week.

General Two Stroke Talk / 45+ racing

« on: February 22, 2013, 02:45:54 AM »

I'm 49. I got my 1st motorcycle at 40, and it was a street bike. At 41 I got a dirt bike and I rode trails for a couple of years. Around 43 I rode my 1st track and fell over all the way around it, but I got the bug.
I'm as fast now as I've ever been, which isn't saying much. I race mx and gp's mainly but have done desert and enduros too. I won my last couple district 37 gp's in the sen/int class. It's all about having fun...and I'm somewhat of a jumper.
btw, I ride with a 70 year old gentleman who races the magnum class with D-37. He still holds a good pace and jumps almost everything....
