My starter wants to star in a movie...

"Deliverance II"

Yes it's starting to squeal like a pig.

Is there any concern for this malady other than attracting horny boars?

I'm ok with the sound if nothing's going to grenade.

What say ye DR Drs?

More power

Hi awesome people, sorry not been around much recently, new job been keeping me busy and not much time but nice to see you're all still here helping people. :-)

I have a quick question... I'm after a little more power and intend to do things in 2 stages but I'm curious if my intended theory will work.

Currently I have a standard motor, K+N filter in standard airbox (I really want to keep the airbox stock) FMF header pipe and standard muffler, carb is Oz spec and standard. It seems to run well, no flat spots or surging, but it would be nice to have a bit more grunt.

So my plan is to add an FMF Q4 pipe, I'm not expecting much if any gains from this but I'm curious if it will still run ok? I know I should re-jet at this point to get the most out of it but will it run like a dog if I don't, or will it just not be performing at it's best? I'm not going to re-jet the standard carb because the plan for the next stage is...

To add a pumper carb ordered set up to run with full FMF pipe, K+N in standard airbox. Will it all come together at the second stage? Is it all a waste of time unless I open up the airbox?

Any thoughts appreciated.

Thanks.

When I was a young kid just out of the Navy, on Sunday night we would sneak over to East Bakersfield, to Cottonwood Road, an all black neighborhood, and crouch in the darkness alongside a church with open windows and listen to the chorus within singing the best damn gospel music I've every heard. Not even remotely related to the church music on the other side of town.

2 choices to rid the noise.... take the starter out and grease the shaft of the armature where it goes into the end cap, or get a Warp 9 Racing end cap that has a roller bearing instead of a bushing.

I wouldn't worry about it to much. Mine has done it when it's cold or I haven't ridden it for a while for probably 15000 miles. I had a 1981 Yamaha 650 Maxim for more years than I can remember and it squealed most of the time I had it.

Thanks! It's good to see what it looks like when that's done right. It gives me a plan of attack that doesn't involve my welding skills (which always requires my skills with a grinder).

If you don't want to cut the airbox, you can always take off the airbox lid. Don't lose the nuts. They aren't fully captured.

You could also try a pod filter, but some people report that it isn't as good as an opened airbox.

Basically, the airbox and the lean needle/idle settings are where you can gain most improvement. In Oz, you probably have the adjustable needle and your idle-mix screw is accessible without having to remove a brass cover. I'd still suggest an extended screw though, to make adjustments easier.

Try just popping out the snorkel, then moving the clip down a position on the needle. Then adjust the idle. You may or may not want to bump up the size of the main. The main may be the only part of the carb that isn't set lean from the factory, but I use a bigger main with an opened airbox.

Main jet experts...Does Mikuni offer a 142.5 main between the stock 140 and the 145 that some kits provide?

You may notice better grunt with just a sprocket change to 14/42 from stock 15/41 or 15/42, and it'll still run 75MPH fine.

There's also always a big-bore, a cam, a ported/polished big-valve head, nitrous, and forced induction on an EFI setup.

Wear eye protection when messing with springy things.

I use a drum-brake spring tool.

Chill, you can spend a ton of money with minimal gains. Do what he said and just re-gear for more grunt..14/42 will give you that.
I'm using 16/42 this week and it's pretty darn long..........I find myself in 2nd a lot even in our fast mountains. They like to rev so don't be afraid of twisting your wrist for more grunt in lower gears.
A few posts ago we were talking about money is better spent on suspension first, because you can out ride the OEM suspension before you run out of steam.

It's squealing like a pig because the bushing is dry and you already knew that. Mine squealed from 10k to 15k, worse when cold. I felt guilty every time I heard it. Lil' Steve already mentioned your options, how guilty do you want to feel? If you're patient, you might be able to get the starter end cap off without removing the CCT, which would be my preference, given the choice. Warp 9 didn't have the end cap available then, so I greased the stock end cap bushing. I regreased it again 30k miles later when I had to replace the CCT gasket. It never made a sound for those 30k.

I used a pic showing how to retract and release the CCT plunger, for those wondering.

You don't have to be around recently, someone is always glad to answer questions, Kommando in this case. If you ride with others (dust), throw that K&N away and replace it with a foam filter. There are numerous threads online explaining why (K&N flows more air because it flows a larger micron dust particle, bad juju).

Safety glasses are an excellent idea. I have a scar on my left eye, just outside the iris because I didn't take the time to put on a pair when soldering a cable end.

All this extra grunt and resulting chain pull you guys want will just bring on the frame failure sooner, like mine




Bit more here:

with repairs planned to commence next week.

Looking forward to your solution.

ETA:
Since all welds shrink, that crack will pull closed when adding a forward (front ward?) gusset.

Nice sprocket cover BergDonk.

Is that other do-dad that protects the engine case plastic?

How many times you straighten that gear shifter well done.
