the correct way on any bike is to adjust sag per the factory standard method

the easy way is to have a helper....

loosen collar nuts on springs on the stand...first

then take off stand and sit on bike with gear on...measure at the frame end where the little screw is for the fender or any fixed point on the frame to the swingarm axle...

note this measurement

then get off bike and note that measurement

then put bike on stand and note that measurement

what you really want is 4 inches or a bit less first measurement or RACE SAGE

you want 3 inches or so less when the bike is on the kickstand, and you want the complete 4 inches when the bike is fully extended

I have purposefully said it this way as its the normal process in reverse...

the reason being is you will know RIGHT OFF THE BAT if your most important measurement, or RACE SAG is off when you sit on the bike upright with a helper balancing the bike and helping you with the tape measure at the rear end

4 inches good, 3.75 ok anything less and you have too stiff a spring or are way compressed on the spring collars...

I have 100mm race sag...which is good...per the pro that rebuilt and revalved an xrl shock for my oldschool 88! jajaja

soo thought id update again and get some advice

it seems after riding 3 hours to work yesterday and testing my "topend" that albeit everything is ok, I am running high temps...

and I wont push the bike like I used too

it seems that the mikuni tm38 has improved performance and midrange, but not topend, and its there from about 1/2 throttle to wot that I am lean as cruising down the highway(yes i know 14/50 gearing doesnt help) but its a desert bike no?) is where I get the highest temps...

I can make the oil get to 290f

sooo

my question is

anybody know what desert racers used to get for oil temps? normally? wuth or without a cooler?

also

maybe my tm38 was not bored out to xr's only specs at 41mm, if so would this be the reason I cant get my stock topend?

the upjet from 210main to 230 was noticeable and I do not have the "flat" or lean spot that I used to feel

I do however notice that my temps did not change one bit! same temps....

soo

what to do?

OIL COOLER? yeah I know...but if I cant get my topend back then whats the point?

the old kehin got lower temps and better topend by about 10mph...

or keep upjetting my main on the mikuni? to say a 250?

xrsonly kits come with a 17.5 pilot and a 240 main

thanks

Thanks Christian, gives me something to work with. Now I just have to talk the missus into hold the tape measure!

motomike14 · 07-10-2012, 07:39 PM

Have you taken a look at the plug? If it is really lean, the plug will tell the tale. I've heard of iridium plugs making air cooled engines running hot; not sure what you have in it, but if you have an iridium, may be the source of your issues. Try running a cooler plug possibly (bigger number = cooler plug). Maybe also check your oil lines to make sure you don't have any pinches or issues?

elsalvadorklr · 07-10-2012, 08:37 PM

thanks man

I read my plug on a weekly baisis and with the new carb after every ride and during

it looks great

I also posted a pic a few pages back..

its on the lean side if good to my eyes

I will be putting a dpr9 as soon as I can get one...that is only for high speed riding

not to be done during normal riding

this heat issue is related to the new carb

also I must mention that my old carb was still in fact rich if you compare plug to plug chop.

ps. no oil line pinched...pump has new seals and check valve....if anything Im extremely paranoid about that kind of stuff...

cheers man

You want a picture ??

Here's a work in progress I've been working on again today, far from finished but taking shape

Stained glass Dodge Challenger

You can't really see the colours of the glass since it's on a board.
This is a LOT of work

Carry on gentlemen...

Guys
I was after opinions on my conrod, i pulled my top end down today due to alot of oil usage, i found the top end in really good condition (the rings are worn out and will need a rebore and new piston ) but there was no damage, no scuffing to the piston or bore so its going to be getting a rebore, new piston and rings, new timing chain and valve grind but im not sure about the conrod as it shows wear through the copper but is still smooth, whats everyones opinions

thanks

How does the wrist pin fit/feel? Some looseness is the normal.
