Can't wheelie anymore :( 07' Rev 800r

brahm · Feb 16, 2009

It's an 07 Rev 800r 151

When I first got my sled, the thing was a wheelie monster it would yank the ski's like nobodies business, but this season it just isn't happening. I did damage the sled early season but have repaired it there was no damage to the suspension (only plastic, and the tunnel but we straightened it). The only other thing I've done is removed the sway bar. I also seem to be eating a TON of oil much more then I remember last season, any thoughts could I be in need of a good tune up (lost power?), or will removing the sway bar alone make it harder to pull the ski's? There is no way I'm putting it back on as I love how it turns without it. Anybody else have this issue?

Oil injection cable could use some adjusting, it's probably stretched.....maybe this accounts for some power loss which explains why you can't wheely. Did you pack on a bunch of weight over the summer?

How do I adjust it? Whats a good amount of OIL? As far as weight, quite the opposite I dropped around 20lb finally dropped below the 200s, Hopefully I'll hit the 180's before the season is out.

Is the belt worn? Belt deflection tight?

Hmm, I hadn't thought of that, I'm still on my original belt on the doo, I just switched the belt on my cat and the sled came alive.. I don't know why that wasn't the first thing I looked at..good call I'll check that out tonight.

I've got an '05 Summit 800 with a 144" track, and on long days with lots of full throttle pulls (seems everyone else has more track than me, so I need lots of pull to keep up) I go through close to 1/2 gallon of oil a day (again, really putting the wood to her). I've talked to several other riders that are similiar in consumption, so I don't really worry about it. I'm not fouling out plugs and performance is spot-on, so extra oil is cheap compared to a rebuild. I guess if your using less oil than me, I'm jealous of you

can you adjust deflection on an 07?

If it's stretched, he'd be using LESS oil???

Tell me you're kidding.

brahm · Feb 16, 2009

what do you guys mean by deflection? I haven't done much except put **** back together after i broke it, I'm not quite the two stroke mech yet as I am with 4s

Catmydoo · Feb 16, 2009

Your deflection is simply how tight your belt is, or how high or low it sits in your secondary clutch.

corncrackerjimmy · Feb 16, 2009

Ive got my deflection set so the belt rides about an 1/8 in above the sheaves. Very responsive.

corncrackerjimmy · Feb 16, 2009

As for using more oil id check the linkage for the oil pump and make sure it is not bound up giving it full oil all the time.

Have you or the shop adjusted your limiter strap,i had a old 650 XLT and snapped the strap,and it was hard not to wheelie,just my .02

No hasn't been adjusted, I'm the only one who works on the sled.

Unless it works differently than my '09 then that's not the way I understand it. When mine went in for it's 10hr check up I complained of high oil usage, the dealer said two things, 1- it's set a bit rich for break in, and 2 - the cable stretches and needs to be tightened. Maybe it doesn't work on a straight pull principle like a throttle body or whatever.....I dunno, that's just what I was told. Guess I should talk less about stuff I don't totally know about.....

No, what they told you was 1/2 correct Nate. If the cable stretches, the oil pump volume lessens, thereby needing to be adjusted/tightened. But since brahm was saying his oil consumption increased and he made no mention of touching the pump cable adjustment, cable stretch would not cause the consumption issue.

Confused yet? ... LOL

I have a secondary light spring mounted on my pump arm to insure the arm retracts back to static position when I'm not on the throttle, just as a little insurance. My '07 isn't oil friendly but I have the cable adjusted to 18mm, trying to prolong the life of my original 800R

Stock adjustment spec is 16.5mm, so I am adjusted richer than spec. Bottom line; if his plugs aren't fouling, oil is not the issue with the power loss/ lack of "wheelie-bility"

My guess is his C-Lite lugs are finally softening up enough to get traction instead of wheelies(or there are enough lugs torn off ... LOL).

brahm · Feb 16, 2009

?? C-Lite lugs ??, if you mean the lugs on my track my track is in great shape no noticeable damage. Hmm I think it may be running a bit rich though, I have noticed it pop a couple times on shut off, although with that said the motor seems to rev up just fine.. hmm.

The track comments were a joke brahm ... I am a huge hater of the Challenger Lite that came on the '07's. I swapped my 159 C-Lite out for a 162 Challenger 9979 ported and my sled was a different animal. Back to your problem though, the fact your sled doesn't lift the skis as easy could be any number of things. I'd suggest going through the sled and do the easy maintenance stuff(if you haven't already). Check chain tension and swap the oil, clean carbs, check DPM and RAVE hoses, track tension and lube the skid ... if none of that works, dig out your clutch press and start the TRA VII nightmare. Hope this helps.

well, I can use new plugs.. I pulled them and they were awful looking.. I cleaned em up and it ran good for a couple pulls then went back to bogging @ full throttle.. well, I wouldn't say bog more "pulse".. I'm still wondering if i'm either running to rich, or dumping to much oil. I have a hard time reading two stroke plugs as they always seem black to me.. Whats the trick.. on a 4stroke, "white = lean, gold = GOOD, black = rich"

My belt while not threading and appearing to be holding up from any obvious "damage" is very glazed the sides are really shiny.. When do you guys replace belts?

on the '09s, every hundred km or so! Haha.

Your plug color understanding sounds right to me.
