That is a sweet machine. Just out of curiosity, does the electric starter have any issues firing up the 500?

I have a set of 4th and 5th gears from my 89. I upgraded to the taller gears so will see if I can dig them up. Ill let you know in a week or so as im away at the moment

Thanks for the reply and info, Unfortunately im running the shorty plug which are over $50 a pop in Aus. I will grab some cheap normal plugs and just leave the tank loose for the testing. That way I can cut them up with out crying

Cheers

Hi, last year i melted a hole through my piston at finke running a 172 main. Sure dont want to make that mistake again so I have gone back to a stock barrel with no porting and cast piston both oem. Can anyone please advise me on which main would be the best going by the following pics? I followed &...

Yep I reckon its one of the best mods I have done to the bike. I got bit in the ass once though. Thought it was in neutral and was kickin it over with the throttle full open because it was flooded, next thing im on my ass and the bike is 20m down the road. Must have been in second

Sorry to dig up an old thread but I cant find anyone that makes a carbon pipe guard. Did eline ever actually make one to suit a pro circuit?

Thanks

If someone has an 89 or newer clutch basket lying around could you possibly grab a vernier and measure the inside diameter of where the main bearing runs and let me know please. Thanks a lot

I have a welded crank that I want replace the big end bearing on. I spent good money having it balanced so I dont want to throw it out. Is it possible for a shop to mill the welds and press the pin out or is it a throw away?? Cheers

Yeah mate, that was me alright. I think with the setup I had I was lucky to make it down. I wont be making this mistake again next year.

Thanks for the replys everyone, the 2 stroke tuning / timing thing is all new to me so I appreciate the info. Unfortunately I dont have many answers for you as I dont know anything about 2 stroke port timing etc. I bought the engine second hand and the porting was already done. I picked up a new pis...

This happened to me a few weeks ago while I was racing at finke. It must have been running damn lean to cause this I guess but the wierd thing is it ran a a peach on the 230klm run down and started fine the next day for the run back but only lasted 6klm. It all seemed to happen in about 5 seconds, I...

I'm in

Heres a pic of my 08 CRF250 finished. It finally seems the headaches have been worth it!

Hey scooter, sounds like george made a meal of yours if you had to rework it. I must have got a bit lucky as my motor bolted up ok. The welds are shit but huge so it shouldn't break in half. Small stuff like not using radius'd tubing is pretty poor too. I have powdercoated mine so it looks alot bett...

I hear ya. Wish I had read up on this lying prick before I bought a roller of him. What a shit fight it has been.

Hi, Just wondering what model airbox boot you used for the 08 and where you got the red rubber mount for the exhaust mid mount point?

how did you come up with the 56% ??? when you get it finished let me know how it works I trawled forum's for ages and found someone that had used this figure in an AF and it was smoother through the midrange to top end. Apparently the stock cranks run between 59-62%. My engine is going into an 08 C...

Thanks for the info, I did get a reply from STR a couple of weeks ago asking if the cranks were the same from 87-01 but heard nothing since so i gave up.

Roosty, do you plan to be set up for the CR cranks anytime soon??

I was wondering if anyone can recommend a place to have a 89 CR500 crank balanced? Unfortunately the place I sent mine to in Australia has vanashed from the face of the earth and taken my crank with them. Ideally I need a long rod crank supplied, rebuilt and balanced. Looking for a balance factor of...

The bike may be a 90 but I think you will find the motor is either an 85 or 86 as the coolant line runs to the rear of the barrel and there is no seperate clutch cover. They have a shorter stroke and run one less clutch plate also

The job on the white one looks good, seems the petcock will still nearly be the lowest point.

Thanks for the info and links, There is very little on the net about actual balance factors so I think I will go with 56% and see how it goes. I want it smoothest in the 4000 - 7000 rpm range.

Hi, can someone let me know what a good balance factor would be for my AF crank? Im going to get the crank balanced but have heard all sorts of numbers from 52% to 74%. If someone knows a figure that has worked well for them that would be good. The engine is an 89 model
