Monster Sproket Question (mod)

[gunsnroses076]

Got a question if* any one knows out there, if i want to increase acceleration and i am mostly a city rider, would i change my front or rear sprocket, and would i ad or drop teeth, and would i have to shorten my chain.* Thanks for any advice.* Hope to see as many riders as possible at the next meeting.

the best to start with is to change the front sprocket to a 14T (on less than stock)

with that you'll get more acceleration from your three first gears but most of all you will be able to use the first gear at much lower speeds in the city without riding the clutch so much. you also don't need to chnage the chain, just adjusting it will do.

after that, if you want it to pull even lower then you can try adding one tooth to the rear sprocket, but you might endup with the gearing to tow a boat... i remember how it was on my old monster, so i went back to 14T front and stock rear. [thumbsup]

You didn't mention what year/model Monster you have so this info may not be relavent, but if you have a 00-02 M900ie there is no 14T front sprocket available for conversion from the factory 15T. 00-02 MY 900's require a flanged sprocket unlike any other years and (so far) no aftermarket companies nor DP have produced a 14T to fit in place of the factory 15T countershaft sprocket. If you have one of these M's as I do your only choice is to add a few teeth to the rear by changing out the rear sprocket for a larger one and fitting a correspondingly longer chain.

ah, that would be why recomended to him that he change the rear sprocket instead fo the front. i didn't know that about the 2000-2002 MONSTER 900.

thanks for this info Markus.

when you say that it needs a flanged sprocket, i'm thinking it could be one like my bike has. the same as a 999 with single bolt in the middle instead of the one with the two small bolts like on my previous 916. would you say?

It's the 2 bolt style one, probably similar your 916 one. When i regeared my bike last winter I looked high and low for a 14T sprocket but I was told repeatedly (both on the DML and by various Duc shops in Canada and the US) that no such conversion existed for the injected 900's. Eventually I found a shop in Baltimore that swore they had the appropriate counter sprocket so I bought it. Had it shipped to me but it wasn't the right part and wouldn't bolt up w/o grinding to accomodate the oddball flange just as i was told by others. I sold it on Ebay and bought a 43T rear instead which BTW is terrific.



* I'm just now doing a search for the appropriate part # and it looks like (according to the www.ca-cycleworks.com site) AFAM has available a 14T that does fit in place of the factory 15T on the 900ie's. Looks like things have changed over the last 2 years and I may stand corrected...
