Exciter knowledge 101

pretty cool,youre guys rear suspensions are killin me.above clutching info has good explanation but obviously the chart is for the newer style,
 

Checked my jetting today had 150 main and 52,5 pilots, struggling here to find some smaller pilots before friday.... seems pretty rough getting them in another size than 50....
 
Prankster buddy, that is just how the pilot jet sizes go. 50, 52.5, 55, 57.5 etc. I know it doesn't make much sense. So a 50 would be the next leaner size for you. Have you tried adjusting the pilot screw to see if there might be enough adjustment there? When adjusting the pilot screw only turn it in very fine increments. Just an 1/8 of a turn will have an effect. It looks like if you turn your screw out slightly it will lean your mixture.

Awesome pic by the way. ;)!

And thanks guys. I'm glad you are finding the information helpful.

Prankster, buddy - that is AN AWESOME PIC! I want a copy so I can set it as my background! And I'm gonna print a copy and put it in my garage, you guys are my inspiration!
 
Thanx stanage glad u liked it! Of course you can have a copy:) Sent one to your fb earlier. If you can´t get it from there just let me know.
 
I was wondering about exciter and hydraulic brakes... i mean the original ones aint that good right? My cousin used one from a srx with very good results, however he had to modify quite a bit to make em work. Is there any "close" to bolt on solution? I mean where u just need to make a new bracket or something?

Check this out! This guy put a new hydraulic brake setup on a VMAX(Not sure what year) - which is more less similar to our machines.

Looks like many people have put hydraulic brakes on all kinds of models. The only fab work is the bracket...

i just did this on my 95 vmax500 le. i got a caliper and master cylinder off this site from an rx1 and made a bracket out of 1/4" aluminum plate. i have some measurments for the holes if i can find them. pretty easy and quick to do.

You´re the man stanage! time to do a little brake search on ebay:) Got another crazy idea the other night... what about a reverse kit on the bastard? Read some threads about it, but no one ever came through with it. What do u think guys,would´nt that be a cool summer project?
 
if you find someone whos selling those brackets anymore let me know,i used to have the dimensions but course cant find em,
 
That guy that did that on VintageVmax is also on this site, I've seen that name here. You could PM him and could get you the dimensions I'm sure... That looks pretty easy to do, maybe that will be a project for next year.
 
cool,thanks.thats when i was thinkin of doin it to,just going to collect some parts and replace my handlebars all at the same time,i used to have directions and a drawing of it,
 
sounds really good! the first thing i´m going to do when the snow is gone is to make a custom seat that fits my 6" riser, then it´s time for the gearing and the electric start. If the time allows i´ll polish the tunnel and all the aluminum parts:) Lots of work but then again, i love my exciter:)
 
You guys already have me thinking of my summer project. I need to find another 88 Exciter for my mountain sled build. ;)! I just like the black/charcoal and red. I guess I could always paint it. Probably going to be a 155". Hope I can make this happen.

Can't wait to see everyone's projects continue to progress. :letitsnow
 
155" sounds good monte! I´m pretty sure u can make it happen! We will most definitely support u along the way:)
 
Honestly, I wouldn't put in a reverse kit. Our sled is light enough to swing around and pull back. Everyone tells me how light it is. Adding more weight with a reverse kit is more trouble and no fun.

I would rather put in a bigger twin engine, such as a 700cc. But you'd need a donor sled.
 
i´m going for a 700 redtop when my engine dies, or maybe a rotax 670... we´ll see when the time comes:) Found an electric starter kit tonight, no more pulling rope for me:) dsc now it´s finally time to use those pics of yours....

I got my sled going today, had some ice in the fuel petcock... Anyway it still goes kind of rich on low rpm (sounds like a 4 stroke), even though i moved the needle clip to second position, and changed the airscrew to 1 & 1/2.. The current jetting is 150 main and 52,5 pilots, the new unis work much better than the previous green ones which is a great relief:) Also changed my rear shock to an öhlin, works way better and everything seems much smoother. Tomorrow i´ll continue my jetting journey and hopefully i manage to make it run much more cleaner than it does now....
 
2 of my buddies got reverse on there sleds,at first i laughed at em,after watchin em back off trailers and wheel around parking lots i gotta admit its kinda cool,if theres a way im sure youlle figure it out,electric start sure is nice sometimes to,
 
yeah i´m beginning to get old u know;) want things to be easy,my father got reverse on his sled and it´s kind of nice to get of the trailer without any effort at all, (and out of the garage). I will search after a way to make the vmax 600 reverse kit work on the exciter. maybe use the whole drive train from vmax 600.... well that would be a later story..

Kind of fed up with my jetting issues now, beginning to be very impatient... want to drive! i´m just foiling plugs and the damn thing sounds like a fourstroke. I should be right according to the sx jetting but it seems way to rich,even though it was -10 degrees today..what can i do guys?

The TM carburetors does not have an "Air Screw" !!
The TM carburetors have an "Fuel Screw" instead and the function is opposite the function of an "Air Screw" !

The "Fuel Screw" controls the low speed air/fuel mixture at idle.
The "Fuel Screw" regulates the fuel.
By turning the fuel screw OUT, you are allowing more fuel to pass the screw,
effectively richening the mixture.
By turning the screw IN, you are restricting fuel flow,
effectively leaning the mixture.

The "Fuel Screw" on a TM carburetor can be adjusted up to 5 turns out.
To me 52,5 pilot jet sounds like way to big for the Exciter engine.

Just use the "SX" jetting as a safe baseline jetting and work your way down from there.
Since the "SX" cylinders are ported from factory and your stock Exciter cyliners are not,
you shuld be able to run leaner jetting than the SX jetting.

Carburetor troubleshooting is simple once the basic principles are known.
The first step is to find where the engine is running poorly.
It must be remembered that carburetor jetting is determined by the throttle position, not engine speed.
* If the engine is having troubles at low rpm (idle to 1/4 throttle),
the pilot system or slide valve is the likely problem.
* If the engine has problems between 1/4 and 3/4 throttle,
the jet needle and needle jet (most likely the jet needle) is likely the problem.
* If the engine is running poorly at 3/4 to full throttle,
the main jet is the likely problem.
