Rear Spring too short?

7 posts in this topic

The guy i bought my 426 from stated right off the bat that he had cut the rear spring to shorten it because he was rather short and stubby. At first i thought, thats kinda nice cause i have short legs, then i realized the bike probably likes the full travel. Well yesterday i was riding my very short trail and when i went to park the bike i noticed the tire had rubbed on my E-series can. Now i do mostly trail riding and was very surprised that i compressed enough to rub.

Soooo....My question is...would i be able to just purchase a new spring...maybe used from a really nice Thumper friend. or would/should I replace the whole assembly?

Thanks

The word is, from the experts, that cutting a spring actually makes it stiffer. Just buy a new spring that's suitable for your weight, they're not too expensive. If the tyre is rubbing on your can, your subframe may be bent, or if not, you can space the can out by putting a few washers or a spacer in there.

Ben: so you think there is a pertty good chance the subframe is bent? It looks like either the guy i bought it from or the original owner (I'm the third owner) jumped it hard enough to get the tire to rub on the fender... :thumbsup:. what will a new or decent used subframe run me?

Mountain man. I will def keep that in mind. I can talk my way to spending $50 easier than $100 (with the wife)

It could be, but sub-frames get bent all the time in crashes, and usually guys just bend them back into shape. You should be able to see if it's a bit off centre just by looking from the back of the bike. The rear tyre rubbing on the fender is normal and easy to do, a flat landing will do that.

ah ok, Since the purchase of this bike i've gotten really friendly with the carb, and valves...but havn't done a ton with the suspension yet. It is really hard to justify spending money on the bike that to my wife "serves no purpose" when we are re-doing a house that we are buying and is taking a ton of money.

I think i may just space out the can and ride it as it for now....the bike isn't exactly a pretty thing anyway, I don't run on the track, and i don't do big air...so it should do me i think..

Thanks, guys :thumbsup:

I have my stock 426 spring if you are interested. Make me a resonable offer and it is yours if you need it. I had the up the spring rate on mine.
