My did the same and then later it went bang topend need a rebuild recheck the compression again just to be safe to save some dollar

bottem end so when it comes to a new crank i now were to start

Piston Speed (ft/min.) a = RPM b = Stroke of Engine (ft) Formula: 2 x a x b Example: 2 x 8000 x .333 = 5328 ft/min Compression Ratio (Total Swept Volume) a = Combustion Chamber Volume at TDC b = Cylinder Displacement (cc) Formula: (a + / a Example: (100.00 + 823.70) / 100.00 = 9.237 Rod Ratio a = Rod Length b = Stroke of Engine Formula: a / b Example: 6.0 / 3.5 = 1.714 Rod Length a = Cylinder Block Length b = Deck Clearance c = Target Compression Height of Piston d = Stroke of Engine Formula: a - b - (c + (d / 2)) Example: 9.025 - .025 - (1.0 + (3.5 / 2)) = 6.25 Piston Dome Volume a = Head Chamber Volume (cc) b = Gasket Volume (cc) c = Deck to Piston Volume (cc) d = Cylinder Displacement e = Target Compression Ratio Formula: (a + b + c - (d / (e - 1.00))) x -1 Example: (60 + 10 + 10 - (823.7 / (9.237 - 1.00))) x -1 = 20cc Piston Compression Height a = Block Length b = Stroke of Engine c = Rod Length d = Deck Clearance Formula: a - (b / 2 + c) - d Example: 9.025 - (3.50 / 2 + 6.00) - .025 = 1.250 Cylinder Displacement a = Bore (Inches) b = Stroke of Engine (Inches) c = Number of Cylinders cc Formula: a x a x .7854 x b x 16.387 x c cc Example: 4 x 4 x .7854 x 4.0 x 16.387 x 6 = 4942.2142 CI Formula: a x a x .7854 x b x c CI Example: 4 x 4 x .7854 x 4.0 x 6 = 301.5936

you can email me you photo if you want i just don t want to stuff them up cheers email is [email protected]

can you port your reed cages with boyseen power reeds if so how do you do it picture if you can i did a search and nothing i wanted came up Cheers Ian

That what happen i think too topend was real shit then by the time i new it was seized lid was for about 5 8mins tops . so if i leave the lid on the jetting should be fine if its off what size main should i go up cheers Ian

both plug look the same :lean did not do a leak test thought

temps around 65 to 100 f and im at sea level i ve only rebuilt the topend only

Hi guys so this time i seized it left cylinder only right was fine temp was around 73.4 F max mods are wiseco pistons(10 hrs old) tommey t6 ,K&N boyseen power reeds ,310 main jets and 30 pilot jets and running no air box lid can some one tell me what happen and what to change so this dose not happen again i think it was because i took my air box lid of and it was not jetted to suite that i was in 5th flat out and then hits 6th and then it bogged and died and seized cheers Ian

hi my mate has and 04 banshee with these mod tommey tr6 pipes K&N filter with the lid on ,boost bottle,wiseco forged piston and vforce 3 reeds the jets are 280 now and where are at sea level do you think these jet are to small and what size do you think he should go any help would be great cheers Ian P.S we are thinking 310-320

Sea level

What size domes would i need for the mods i have .mod in signature + vforce 3 reeds running pump gas 98 octane that what in australia

Thats what my did and then just run shit and would not go when it was under load or reved up. It was 2 stuffed ring (EACH PISTON)and 2 cracked piston it was hard to start and was blowing smoke and lacking power cost me $205 Aus so it wasn t that bad

Hi guys my bike was not running wright so we pulled the top end off and the top ring on each piston were f..ked and both piston had cracks in them i brought a top end rebuild kit of ebay (std bore)the bore is ok and it is still standard here is the link to what brought is this right (i hope so ) cheers Ian http://cgi.ebay.com/ebaymotors/WISECO-ATV-...tem120173201045

The shee is becoming real hard to start latley what could cause this i have cleaned the carbs out and it was ok after that went to take it out for ride and it would not start (only its pushed started),my thought is that im oilling the filter up to much and its suxing in the oil , could this be the problem of is somthing else im mite check the reeds and see if 1 is open a little as well any info would be grate CHEERS IAN

carbs got a bit of sand in them and my bike was hard to start and was running shit cleaned them out and it starts frist kick but how do i know it has not done any more damage there was no sand on the reeds don t think it got past the carbs i hope any info would help cheers Ian

THAT LOOKS LIKE SHIT THATS NO A YAMAHA ITS YAMANDA LOL

I think it sic keep up the good work and keep posting photos and vids for us

thats what i thought know what is the best way to claen them is its just by cleaning the jets out

bike ran good all day yesterday intill i ran out of fuel (none left at all ) filled it went for ride runs like shit i haven t had a look at it yet but i think mitebeblocked jet or dirty plugs what do you guys thinks ithinks it was dirty fuel Cheers Ian

what size pilot jets should i use mods are boysen power reeds, boost bottle,k&n,no air boxs lid,toomey tr6's i have a 310 main and 4th clip on the needle and stock pilot(25) if i but a 30 pilot in will this stop the bogging from idle to 1/4 or1/2 throttle or do i go up one clip im at sea level with temps around 20 to 30 deg

there is a place NOR called tamala park got big sand hills like lano its like 10 min from ythe end of the fwy still a bit og a hike for you thought of there was a place at thomas rd and rockingham rd, that if they still let you right there

Some people cut out the back 2/3 of the lid, opening it up. DONE THAT.Some people buy a pro-flow kit GOT THAT I got my bike jetted by a motor bike mechanic and he made it a slight rich he said for the hot weather we had in summer now it a bit cooler should i go down a size and another thing were is the pilot jet located so i can see what size it is. Thanks for your help too man

So if i leave the lid off it should be ok . Im runninbg at se level too with with temps around 25 to 35 degres Cheers Ian
