Keep the bike man. I have both a shee and a 450 and theres days when the 450 is put aside and the shee is let loose. 2 bikes is better than one especially when you going to get ripped trying to sell a perfectly new banshee and will get pennies for it.

Thanks guys

Guys I've also got this problem with some replacement TRD reeds. Ive tried flipping them but they still wont seat fully. Will this cause any problems ? Sorry for the dig up of an old post but I did the right thing and searched before posting a new topic

P.M'ed J.J

Thanks boonman again. I'm going to check these reads and look right through the boots like you said. I suppose it won't be that bad just to replace the reads and boots now. They are 3 years old.

Thanks for the replt J.J. I did the soapy water trick and didnt find a thing. I've also removed the cluth cover and tried to get find a leak on the crank seal on that side but didnt. A few more tests later and Im still only dropping 1/2 to a 1/3 psi in 6 mins. It's pretty late herer now so tommorrow im goling to check the reads and carbs. Hopefull thats goin to be it.

Guys I tried a leak test but Im getting different results each time. Its beginning to really shit me. I blocked both exhaust exits, and made up plates with fittings to bolt over the read cages because that was going to be easier than finding pipes and fitting to use the carby boots. Anyway, whats happenning is with the first test ( im pressurising becasue I cant get hold of a vacum device here ) I pressurised to 6psi and in the 6 mins it dropped about 1 psi. In the second test, it dropped 1/3 of a psi and in ten mins and in the third test, it dropped 1/2 bar in 10 mins. With those results, is that acceptable or not ? I dont know waht the range is so to speek for leakage or is no leakage what we are after here ? Im starting to wonder if the reads are buggered ( They do look ok but im no pro on them ) or if I have blockages in the carbs, but ive cleaned them many times. Can anyone help me with this plz..

Thanks Boonman. I'm trying to get some gear together to conduct a leaktest but its bloody hard to find the stuff were I am. I was hoping to replace all the seals and gaskets to eliminate the problem without doing a test. I have gasket kit, and seals plus some tight joining surface gasket silicon which I persume is for the gear case. Also rebuilding the carbs with all new parts and gaskets will hopefully eliminate them. I'll just rebuild the engine tonight and see how it goes in the morning

Hi guys, My motor's got a air leak which is causing it to run lean up high in the rpm's ans splutter etc. I've just recieved a full gasket and seal kit from vito's performance ( top mob ) but was wanting to know if I can change all the motor seals out without having to tear the engine down to much. From experience, does anyone know if its more likely for the seals to go before the gaskets and let air in the motor ? Im hoping to do a quick fix ( like the seals only ) so I can get out and ride. Im not really to keen on splitting the gearbox apart if i dont need to. Any comments/suggestions or advice would be greatly appreciated before I rip into this

Thanks for the replies guys. The verdicts still out though

Hi guys, I need some help trying to figure out if its still worth purchasing my ordered 05 YFZ450 SE, or cancel it and spend the cash instead on modifying my current banshee ? The reason I ordered the new 450 was to race at my local MX track against lightly modified Raptors, Shee's, 450's and Z400. I was going to spend additional money on the 450's suspension, motor wheels etc etc and it will/would cost me a small fortune. But I'm thinking the bike might be way over the top for the local scene. It would end up being like a Pro-production bike. My question is, do you think I should cancel the order for the 450 and spend ~3/4 of that money from the 450, on the banshee doing it up to race that instead ? That way I can save a bit of money and still have a bloody fast bike with a hot engine and the suspension to match...... All opinions are welcome Cheers guys

Thanks tats4life but I've just started replacing the bugerred crank seals and I have t-5's on the way to replace the stock exhaust. I went to my local motorbike shop here and put and order in for an 05 450F LE and was told before the end of the year I'll have it so I still got a fair bit of time left to roar the banshee around before my mate buys it.

Thanks again Banchetta, It looks like I have a crank seal leak as I cant find leaks on any other and with the startor cover off i can hear I small hissing sound around that area, so it looks like its the stator side seal so far. Im going to replace the seals, and gaskets on the bike, fix the leak and then put new pipes on it and sell it to my neighbour who absolutly loves the bike. I took him for a ride once and he's been waving cash in my face ever since to buy it off me. I might one day buy another banshee for its pure thrill two stroke ride, but for my local motorcrossing I need the 450F because I can lap my local track 5 secs faster on it that my banshee. On that, does anyone know if theres a forum thats as good as this for information on 450f's ?

Yeah imagine that cost $$$ !!! honestly, it will cost me ~ $600 AU to send it to and from the west coast. Thats a fair bit of dosh just for freight so thats why Im asking if DRacing are worth the effort. They look like it

OK, I did the test and I have a leak but not sure exactly were. I would of thoguth I could find it easily with it losing 6psi in 4 mins ( It suppossed to hold 6psi for 6 mins ). Ill need to futher investigate but the engines out of the bike and Im looking into sending it to Duncanracing to have the national kit work done and get them to rebuild the engine totally. Has anyone had any personal experiences with DR and their engines ? I would like to know as they look hell professional and I dont want to be sending my engine to the states to a crappy builder. P.S: Banchetta, thanks for the spot on diag's
