Thanks for the advice, if it was my bike i'd give it a go but i daren't try it on someone else's.Got it off in the end,decided to remove all four M6 studs so i could rock it to and fro.One of the dowels was stuck.Going to change the base gasket as well for peace of mind.Asked the same question on XJR1300 and got nothing! Thanks again.

In the process of removing head from '99 XJR1300sp for a mate who managed to strip a plug thread.Most of it came apart easy enough but the head is well and truly stuck to the barrels.I've removed the m6 studs at the front but the ones at the back aren't long enough to double up the nuts to lock them.Done the usual tapping with rubber mallet etc but i think any movement is going to disturb the base gasket.Are they usually this bad? i've done CBX1000 and GSX without having to resort to bigger hammers! Any ideas?

Thanks Tony, the bike hasn't been run yet since rebuild.It's on a lift/bench so it is upright and level.It's a learner bike but i'm 50 and have experience of rebuilding 2strokes (maico,husky,Sachs,RM,CR,YZ moto-x,Gasgas,Bultaco,Fantic,Beta trials plus GT,RD etc).Looking at the crankcase with the clutch cover off and measuring where the sightglass level would be it looks like the oil level should come to just above the selector mechanism but i just can't see an obvious place for the oil to get into the gearbox.........more tea and head scratching required!

Hi, new to the forum so hope someone can help. Just rebuilt an '88 TZR125 (2RK).Engine work included rebore and crankseals which i did while the engine was out but without splitting the crankcases.When i was filling the transmission with oil the sightglass showed it full with only about 400cc of oil.As i was expecting to put 750-800cc in it i'd actually filled it above the sightglass before noticing.I drained out the excess until it was at the right level which meant it only had about 400cc in it! There is no loss of coolant and only clean transmission oil came out.Removed right hand (clutch) cover and clutch to investigate.Does the oil pass through the small hole above and slightly left of the gear selector ? if so it looks like something on the transmission side is covering it. Any advice would be appreciated.
