2001 Blaster bogging and backfiring

[Big Buttery]

I was cleaning my air filter a couple weeks ago and something got caught in there and pocked a hole in my reeds but it still ran fine. I put in new reeds and stoppers and it's still having the same problem. I tried adjusting the carb but it still does the same thing. It idles fine but won't rev very high. What do you think I should do? I pulled the head off and everything looks fine. Have no clue.

Sounds like your reeds are jacked, or your jetting is way off. Look into both of those, and you should find an answer. Take some pics, and give a list of the mods you hace done to your bike, and we can help you better.


BTW, how was the birthday party?

Is parking break and tors still connected ?

Party was good and it has stock jetting I'm pretty sure and
The only aftermarket part it has is an FMF Fatty.

I am afraid that stock jetting is not good enough for a FMF.

The FMF alone calls for a 260 jet!.

I'll take it apart when I get home and see what jets are in it. But I'm pretty sure there stock.

I'm way curious how you poked a hole in a reed while just cleaning the air filter.

Any time you have ANY part of the top end apart, you NEED to do a leakdown test.
Anytime you have unidentified running problems, you need to start with a compression test and a leakdown test.
It amazes me how many people pull the head off to have a look when it's not running right. What are you expecting to see?

I think something fell in while there was no air filter. I was thinking there might be internal damage. However, I noticed oil leaking out of the head gasket so I know I need to replace that.

Ok, back to my bike lol. What do you guys think of me getting an FMF power up jet kit or whatever its called?

 

[Blaaster]

Forget a jet kit, they seldom contain jets of the correct sizes, or sizes that are usefull.

Buy individual genuine jets only.

Ok, I'll take it apart tomorrow and find out what jets are in it. Haven't had time yet but I'll make time. What jets do you think I should get?

 

[Big Buttery]

So I just took it apart and im running a 260 and a 32.5 what do you think? should I go down to a 250 or 240?

 

[Blaaster]

The FMF alone calls for a #260, any other mods or pre mixed fuel will need larger main jets.

List all the mods, your elevation and average temperatures.
