Yea Jeff, went and looked at some of the threads he started. Troll! Asks a question and then gives his opinion over and over. Hope he finds the correct oil for his pre-mix in his trials bike.... someday.
Weird that you feel that the definition of a troll is largely related to the fact that the said "troll" almost certainly has far wider and more accurate knowledge of 2T motors than you do? I guess the net has afforded the opportunity for all sorts of clueless bullshitters to set themselves up as instant experts, and these types tend to get a little annoyed when lack of first hand experience and no info on the net for them to cut and paste, shows them in their true light!
Unless you have a strong desire to waste time and money, there is no real need to replace crank seals which are perfectly serviceable, in the hope of curing a problem which in many cases will not be related to crank seals at all. Its very easy to test crank seals, and it will take maybe an hour to put together a cheap home made pressure tester set up, which in many cases will confirm that the seals are good. First thing to check on bikes which have been standing for some while and have a good spark and compression is the carb. Again very easy to do this.......... simply remove the air cleaner hose, squirt aerosol brake or carb cleaner into the carb mouth, and see if the bike starts. If it does start it will obviously only run momentarily, but this will confirm 100% the problem is with the carb, and has nothing to do with seals or anything else suggested by the net based experts.
Thanks for all the advise. (I think) I've got a line on some crank seals, and the advise to use a local bearing suppler vise a bike shop is very helpful. I got it from here. Thanks everyone.
What did you find in the end with your crank seals? I think I have the same problem...bike runs ok but not with the cover over the carb on.
Ive been working overseas for most of the year. So ill tackle it during the long Minnesota winter. I've going tp replace the left side crank seal and hope for the best. Sent from my SAMSUNG-SGH-I317 using Tapatalk 2
