could be ive never set one up before on these bikes ive followed the instructions that came with it and i took my old one apart but ill do it again tomorrow double check

should i send it back and get a new one? it has a 60 day guarantee

would it be better with the valve out completely?

Thanks just waiting for my bearings to come and it can all go back together cant wait to ride it with the 170 kit on been a week off road so far

Ive put the power valve on the 170 barrel and when i tighten the outer casing and tighten it the valve wont move atall untill i untighten the 2 bolts any ideas?

thanks im just waiting for the bearings now then i can put my crank in then ill fit the 170 kit its all coming together nicely now ive been pushbiking it 45 mins every day to work so i cant wait to back on road haha

Engines split now just waiting for my bearings

you might need a different spark plug a hotter one and u would have to up jet the carb find what jet is stock and order the next few sizes up its pretty much trial and error from there

It bent when i was flipping the frame over trying to tap the pivot bolt out and forgot i left it on goto wait for this to come aswell now delayed me by another day

Its a 88-04 engine

Does anyone know what the part number is for the throttle needle or were i can order one ive checked ebay and they only have the 175 needle ive tried allen carbs and they need to know the part number and i dont have a clue what it is

ive removed the engine and have taken all i can at the moment the clutch and some primary parts are removed going to use my local shops air wrench to remove the transmission side and fly wheel as mine wrench is broke (knowing the shop owners a plus) im installing a new crank, ebc race clutch kit and the athena 170cc kit i will upload pics of stages so anyone else wanting to split there engine has a rough idea im just going by memory on here never had a dt engine open before looks simple enough though. im quite surprised the inside of the engine looks as if its new! this is what i emptied out of my exhaust not a nice sight nice con rod there must of been pretty old... casing looks new you wouldnt believe its a 2004 engine removing the clutch was really easy you need a 8mm for the springs then the front plate just pops off with a flat head and you remove the clutch inner plates just by pulling them out, i used a clutch/flywheel holder tool to hold the clutch in place while i got a wrench on the bolt you can just use a air wrench or electric, be careful as there will be some sneaky washers there! with the clutch removed i took apart what i could i will be taking the other cogs off tomorrow and splitting the engine new crank should be installed wednesday (thursday latest) few compartments i removed in my storage box the kick start drive, springs, part of the gear selector, front sprocket, clutch leaver part, and flywheel and clutch bolts + few other little things. engine so far frame without engine or forks (there at the shop getting new seals and oil) cost £30 i removed my 2 stroke tank and other things just for cleaning purposes they had so much old oil over them i will be adding more pics tomorrow or the day after my athena 170 kit has came and looks great just waiting on the crank and bearings now

when ive taken bikes to the track i just wedged a block of wood or a brick on the front wheel and strapped it down one on each side hooking the hook on the left and right side of the handle bars and strapping it down tight, and also one over the seat and your all done

Owch i always use rock oil for all my 2 stroke and gear oil anyway, im going to put 2 cap fulls for the first few hundred then 1 cap after wanna wear it in properly ill line the barrel and piston with a light layer of 2 stroke aswell

Hopefully it runs fine im going to mess about with the carb untill its perfect im booking my bike test and keeping it whille i have the 2 year restriction so its goto last im hoping i only go through 2 pistons max going to try change before it goes to maximise the life of the barrel and change the oil and air filter every 2500 miles

yeah ive ordered the 170 kit, new bearings, the crank that had 4200 miles on, a new ebc clutch kit, some odd and ends some jets for my carb. going to read up but i know my way around my bike now stripped it down and had the engine out within 3 hours of it blowing up (considoring i had to push it 20 mins) should beable to do it im going to completely tear down the carb and give it a clean what jet would you reccomend me trying with the kit ive ordered 230, 240, 250 sizes, im goingto borrow a flywheel remover tool off my mate and a clutch holder tool and split it monday the day my crank and bearings come ill freeze them and build the bottom end back the day after then await my 170 kit

Ill order the second one when im home then just been to my local bike repair shop they said my barrels past re boreing looks like ill be getting that 170 kit sooner rather than later

yeah think i will i could order a oem one just to be on the safe side but £300 for a cranks alot to ask i cant seem to find any second hand ones for my bike there all for the older lc ones

108 quid with free postage

i was just wondering is there anyway to get the newish style plastics to fit say from a 05 style dt or just anything newer than the 88-04 shape

The conrod kit and re pressing service and postage is pretty much the same price might aswell buy a new one

Yeah i dont know how many are actual mileage but im guessing alot i can only find a top racing crank its an orignal replacment but they quote its of a better quality do u know if there any good i used there make on my speedfight crank and that was good but its only a 50cc i dont know how it would be in a 125
