Rs vector mountain no power since turbo was removed!!

[Vector88]

Hey guys
I recently picked up a 2005 rs vector mountain which had a bender stage 1 turbo kit on it. When I bought it the kit was removed and was told it runs and idles fine but has no power . I managed to get it on the trail to see how it was running and I can get around a quick 90 kph out of it but it don't seem to pull like it should. I was also told by the previous owner that there was a head shin in the motor so I am not sure if that would cause this problem. My plan is to make this sled stock with aftermarket clutching. This is my fist attempt at this sled as this is a project for me over the summer. I still have to check the carbs jetting and adjustments. Also I do plan on removing the head shim so would I need anything besides a new head gasket to tackle this job? Any help will be great guys. Thanks

I would do a compression and leak down test on it. I would think a head shim would kill your mid range punch without boost.

I'll tried to do a compression test and I don't have a 10mm adapter. The smallest I have is 14mm which sucks. I'll have to order one in since napa don't have one with a 10mm adapter in stock.

Did you check the carbs to see if all the jetting was put back to stock? How about the clucthing?If neither of those 2 things where done it will be a dog.You are going to lose a lot of power too running lower compression naturally aspirated and it probably won't pull the stock clutching either

 

[Vector88]

Yeah I would say my best bet is to remove the head and take the shim out. I was told that this turbo didn't need a shim

I would... its going to need the compression in stock form.

While you have it apart put in the updated cam chain tensioner.

Timing might have been changed when it was turboed, as well as the head shim, clutching and jetting.

 

[Vector88]

Yeah I plan on doing the updated can tensioner when I remove the head shim. I looked at the stock specs lastnight and the guy that had it didn't change the jets back to stock after removing the turbo. The 148 jets were in a little baggy in a box of parts. I'm unsure what jets are in her with the turbo. Also I think she got a heel clicker clutch kit along with a blue secondary clutch. Think it is a team secondary clutch. Would this secondary be any good to me if I'm running stock with a little bit of clutching done? I'm still in the process of trying to tear everything down to find out the gearing also.

I did a little work tonight I found out the main jetting which is 165 opposed to 148 stock . Also the head shim is roughly 1/8" thick
