Adventurer 900 triple 1999 needs some luvin.Read the haynes and do we need to do all this.Remove clutch assy ,waterpump,drain oil.Any tricks to make life easier and get me on the road again.
Is the front sprocket an oppisite thread,left hand.
Any advice as I am goin to change front sprocket up to 19 teeth and one down at the back 42 teeth to lower touring revs and engine noise.
mant thanks for all the replies,try to keep them clean thanks.

hi , yes totally agree.cant access the area without removing the clutch system / sidestand and sometimes the waterpump as everything is crammed.I have since started the job but failing due to having to order new parts / seals and gaskets(tried to avoid).The bike is in bits and so am I.The postion is started not having a leak of oil bit looks like im gaining one!The job was complete after 4 hours work but weeping oil hence the new bits.
Anyway lets see how I get on, thanks for the reply if any body else is in this position I will pass on my experiance thanks gents.

 

Hi Mate, thanks for the reply.Trying to do the job as it should be done with good triumph replacement parts but other forums imply even having stopped the leak initially one comes back after a few hundred miles.I am in the process of carring out to the letter and completing the job, lets see if i start with sucess and end in failure.Stay safe thanks steve
