Hi all, been a while since I've been around the 2 stroke scene. I have too many bike for one man to keep in the condition I prefer and also ride. This is far to cool of a machine to sit in my...

So its that time again, fresh crank and top ends. After numerous times at the plater and a few "repairs" that required decking the cylinders without my knowledge I have short cylinders. I have a .4...

I was out last weekend at Grattan with soft / soft only got about 20 laps in my tires are super smooth. Low 1:31's. It looks to me like its the ultra soft just wearing more quickly. The new surface...

rotax is still fighting our fight. Its nice to watch but people are still buying into the 4 stroke hype. I will be buying an 800 etech this season or next, but most of my friends are riding 600#...

I am cleaning them as well as I can with the engine in the bike and the piston still on the rod without getting anything in the crank. Not an easy task I might add.

The front cyl was replated...

4DP rebuilt Winter of 08 with fresh crank and top end. Had a busy summer of 09 and did one track weekend. Front base gasket started leaking first day. I replaced it that day and the rest of the...

I'll call your 11 months and raise you. I am waiting for a crank rebuild I sent in 1-20-09. Still waiting!!! Good thing it wasn't anything important like a CRANKSHAFT!!! Things are starting to get...

I would love to go to Rich Oliver but just don't have the cash or time to travel across the country.

I'm going in September and looking forward to backing it in all day...

I'll be out there for a couple track days 8/1 & 8/2 burning some 747 and rashing some stones. It would be great to ride with another smoker...

Damn, My bikes a fatty http://www.tz250racing.com/iB_html/non-cgi/emoticons/biggrin.gif

Just wondering where I stand?

My 4DP with carbon skins and some Ti. 235#'s
All fluids no fuel
Sounds heavy to me 220 sounds much better.
Is 5KE lighter?
I don't know where to lose any more...

Well .75 psi in 5 min is where its at and where it will stay.

I didn't think about the egts. not thinking gets me in trouble sometimes

They just repaired the top of the cylinder so it all came off the top. I went from a .6 base gasket to a .8 and got my .025 squish so I called it good.

I don't like doing this but I don't think I...

I know this has been discused a LOT but no one has given a specific standard.

Is it just zero?

I just don't want to have a failure.

My lower cylinder holds 5psi for two hours. I am happy...

It is with regret I am making this decision to sell my NSR. I have a TZ and NSR and as they are very alike they are also very different. The biggest being ease...

So, I just got my cylinder back from repair / plating.
It is .009 shorter. This may not matter with .040 squish in another application but I run .025 squish .009 is a lot.

I was instructed not to...

I have the 6/19-21 off work for the Grattan AHRMA race what else do I need?
My bike should be...

They just take soooooo long to get things through. I buy a lot of snowmobile parts from our friends in Canada and it always take a long time. It always takes a couple weeks each way.

Just wanted to say I sent my rotor to Frank and it has so far been one of the best experiences with a vender I've had in a long time.

I can't wait to get it back!

I hate customs...
