ok, a lumberjack. i get it. since i started using Husky saws in the the '80's (266 & 181 models)  i will call myself a chain saw amateur.

admin, i'm just kidding. every oil thread i've ever seen on the internet turns personal. i hope this place is different because honestly someone could run canolla oil for all i care.

First of all.. Nowadays tracks are way more technical than the past..

You need to take a look at some of the mid-early 90's sx races.  The tracks today have ramps not jumps the tracks today have rolling braking bumps not pizza slice, do or die, cant roll them cause you would high center WHOOPS!

I remember going to sx in the early 90's and you would be hard pressed to crawl up a jump much less walk up it.  This change happened in the early 2000's because a certain up and comer couldn't time a jump to save his life but he can twist the trottle just fine, until he hits the ground.  The ama wants their to be a "super star" to do to the sport what McGrath did.

the best SX track last year IMO was the one LaRocco designed. straight out of the '90's it had no spots to rest and cruise. it was so busy that the 250F guys were visibly winded when pulling off after the race.

out of curiosity,how well has your friends bike held up?  Is he running C-12?  What oil and premix is he using?

the engine has been the model of reliability. of course it helps that he bought the bike brand new in July '02 as soon as the '03's came out. i tore the engine down in late fall '02 and he sent the cases, head, cylinder to Renyard. one cool thing about that bike is you can do a top end or re-ring without taking the head loose so you don't have to buy a head gasket. he buys a 55 gallon drum of 113 Klotz race fuel and blends 50/50 with pump gas to make around 100 octane and mixes 32-1 with Redline. he also runs a PC plat. II pipe and 304 silencer. the stock rims cracked after two seasons and the stock alluminum spoke nipples were junk from the get go. the spokes never stayed tight and required constant adjustment even between motos. i laced up a set of excell rims with Bucahnans (sp?) stainless steel spokes and nipples and after a couple of rides they stayed nice and tight. the bike didn't get ridden in '06 and '07. he broke his wrist on the first ride of '06 then got married and didn't ride in '07. so the bike has about 5 seasons of actual use on it. the Keihin carb was added last season. he got it for $50 off ebay.

a guy i ride with has an '03 CR250 that Robert Renyard did the head/cylinder/cases on. it does rip pretty good. it uses a  stock YZ250  'D' piston with the "windows" on the skirt on the intake side. thats how Renyard set it up. it also uses two base gaskets which was the 'outdoor' setting. the cases were stuffed with epoxy. the other thing my friend did was replace the stock Mikuni with a 38 PWK Keihin as it stabilized the jetting. the bike seemed very sesitive to small changes in conditions with the Mikuni. and you are right about Factory Honda wanting to know what Robert Renyard did to son Robbie's CR250. when Robbie as a privateer went 4-4 at Mt. Morris ('02 or '03, can't remember) the factory techs went to the Renyard pits for a little chat.

being a teenager i imagine money for maintence/repairs is harder to come by than someone who works full time. if that's the case the most economical way is a Jap bike. tons of aftermarket parts and dealers are everywhere. most of the engine parts like pistons, rings, rod, bearings,seals & gaskets are cheap and readily available OEM or aftermarket. you can stretch you $$$ farther. personally i would rather a Husky but i like Euro bikes and i can afford the sometimes outragous parts prices. dealer support for Husky is spotty.

General Two Stroke Talk / Re: Frame weight difference between steel and aluminum

« on: January 14, 2010, 05:08:24 PM »

i just hate working on aluminum frame bikes. everything is so hard to get to with those huge spars. as far as air cooled engines, i remember how they over heated in slow going/hard use and then the jetting was all over the place when hot. i don't miss air cooling at all.

if your clutch has aluminum drive plates you can replace them with steel. gives the same effect and it's cheaper than a flywheel weight. i used to do this with CR500's and KX500's. they didn't stall as easily in corners and when kicking over the extra mass of the steels kept the engine turning over longer per kick allowing it to start easier.

That's not as much frame flex as it is the rubber mounts the carb hangs from.

Not questioning the quality of the work done by Dicks.

Your post proves my point exactly. The external main jet should HELP, regardless of altitude. The problem is, the rest of the tune up wasn't corrected to use the external main jet.

If a bike comes to me with one of those on it, I take it off. If you make the changes to get the external main jet to work, and the customer gets to look at what you did (or worse yet, one of his buddies, who is a guru whizz bang in gym shorts tune up guy in his own mind sees it) they flip their collective lids, change everything to what they think is right. Now you just wasted your time, and you get blamed because the tune up is off.

actually the "rest of the tune up" was corrected to use the external main. did quite a bit of testing to see how lean i could go on the main and needle and ended up running a much leaner needle too. i ran the set up for about 6 months. it did run fine with the dial-a-jet but not any better than without it and 'regular' settings. "guru whizz bang in gym shorts"? LOL

i had this done to the carb on my '99 KTM 380SX. i mainly ride MX and the problem i had was when landing from a jump the brass fitting on the bottom of the carb would contact the top of the engine cases and it cracked the fitting and gas leaked everywhere. when looking at the bike on a stand there seemed to be plenty of clearance between the fitting and the cases but that just shows you how much the frame and engine actually move when taking big impacts. i ended up taking off the dial-a-jet as in my local (no elevation changes to speak of) it didn't really do anything. i think if you lived out west where you rode at different altitudes in the same day it would come in handy. i bought a new float bowl for the carb because of the cracked brass fitting. the bored carb did make a difference you can feel and of course i had to run much leaner jetting. Dick's does do very high quality work. i still have the bike (i bought it new) and it was retired from MX back in '05 when i got a '05 250SX. i still use the 380SX for the few trail rides i do with friends every year.

I would like your opinon. I've been using Pj1 gold fire but its getting hard to find around here. I'm looking to switch to an oil thats easy to find here. The main choices are Yamalube,red line, All the Maxima oils,Belray ,Motul,golden spetro. Thanks

i find Yamalube, Belray MC-1, and Golden Spectro to be diry with too much carbon build up. as stated the Motul 800 is very clean and so is the Redline. all the oils will protect your engine some just burn cleaner.

Villopoto had a cold according to some of the mainstream mx-websites

He may have had one, but, he still disappointed me even last year.

he won two SX races last year (on 450's) and the blew everyone away at Glen Helen before he destroyed his knee. i think he will come around.
