Hey guys,
I want some input from people who have used a flywheel weight on a RM 250 before. I just picked up a mint 2004, and want to get it ready for the season.
Back story: I ride 90% moto, and I am a top 25% +30 intermediate rider.
I first was introduced to a FWW on a 2006 RM 250 I had for a short time. It came with a FWW and I rode the bike at Budds and LOVED it. Everything about the power delivery and traction. I then took the FWW off and traded it to a buddy for a nice DEP Works pipe. I rode the bike one more time, and was not happy. It was a dry, hard track which is tough on a 250 but it was noticeably different.
I then picked up a 2006 YZ 250 and rode it a bit. Put an 11oz weight on it and loved it. Traction improved, it got smoother, and honestly felt like it pulled harder, longer. People say that it makes their bikes feel slow, but I always keep my bike in the upper RPM's anyway, and never noticed much of a "laggy" feeling.
Anyway, I have read mixed reviews on the RM 250 FWW, so I was wondering who has used one, and what weight do you recommend? I was planning on doing a 10oz, but I want to make sure.
Thanks!

If you have an 04, look for a carb manifold, read and spacer from a yz250... really helps how the engine runs.
The ports and power valve are mismatched, so you can clean them up as well.
When you have the cylinder off, check the reed stoppers aren't blocking the rear boost transfer port... this is where the Reed spacer helps, the yz250 manifold is shorter and keeps the spacing the same

On my 2005, I preferred the yz250 OEM reeds over the vforce, cant remember whether I modded the stoppers to clear the boost port .
I like factory fatty best with the stock silencer of all things... stock is exactly the same dimensions as the fmf regular silencer lol
I'll probably go 8 just to be on the safe side and ride it back to back a few times and see what I think.
My buddy bought n 05 last year, it had a FFW on it, took it off couldn't really notice any difference his a an 8oz. He's running the same PC works pipe and R304, both bikes are buttery smooth.
He dumped his 17 Husky TC250 for the RM....
Were both upper end Vet riders, like in our mid 50's...
Here is one video if you want to check.
In the video i run in 3rd gear and 4rd
Yours builds are awesome spagina! Cant wait to see the bike finish
here its a zone a litle bit arid and the video was taken almost in summer and the track is closed many yesrs ago. not rain so often where i live and sadly youre right, its like a desert most of the time.
Pit Row
Anyways, I will be riding some woods and racing harescrambles this year for the first time since I was 12, so I just want to smooth out the power a bit. I'm going to get an 8, because I found one used on ebay. I'll ride back to back a few times, and if I don't like it, then ill get rid of it.
