Ok internet. Need some help and advice here (gasp) what you see here is a 38mm H series lectron carb on a 2001 rm 125 with a vforce reed cage. It appears to be an extremely tight fit ( might be able to get in there a little closer) you can see how close it is to the shock. From what I have read here on vital is that this is the issue coming off of a vforce cage. I'm sure it would fit fine off of the 20 year old stock cage but that's going completely backwards right? I've read that boyeson rad valves are shorter? What would you do ( this bike has been running exceptionally well since July) I thought this would be a cool trick upgrade for this bike but maybe it's not? Also, 90% sure this carb will be for sale! 375.00 shipped !
