ogre:
i think so had another go today got it warmed up checked timing with strobe light inconclusive could hardly see the marks put it down to being very old and could be a bit of vibration it definitely advanced when i revved it this time though i put a fan at front of bike which seemed to help didnt hesitate as much i synched it again as i just started to open throttle and i have had to set 1 and 4 to 2 and 3 there is a bit of play in the carbs but not a lot possible bigger problem now noticed a very small oil leak coming from head gasket  talk about gutted checked the 4 head nuts you can get to next to spark plugs and werent tight torqued all the head bolts up twice on the rebuild can't believe it which i have tightened up but worried now about the ones i can't get to without stripping the engine again whats your thoughts on this can't believe for all the ground breaking design honda put into the engine for its day they never thought about being able to work on the engine in the frame

Bryanj:
It was supposed to be 100,000 mile reliability(IF SERVICED PROPERLY) so why would you need to work on it

ogre:
didn't know that but ford say my ford focus tdci estate will average 56mpg its never seen it they also say theres no problem with the dpf on them but we know that isnt true dont we unless you boot it every where and you live on the motorway

SteveD CB500K0:
My FF 1.6 TDCi does 59mpg average when I drive it to the other end of the country on the motorway (at 70 mph)

I've tried to get it up to 60 mpg but never quite got there.

Normal use = 45-49 mpg...

ogre:
urban 49mpg extra urban 74mpg combined 63mpg do a lot of miles on motorway thru work tried tickling it everywhere even neutral down hills my best combined was 51 mines an 09 had a bit of banter with my mate at work whos got a 56 to be fair he got better than me his best was 53 dont get me wrong its not bad just not quite what they spec it at but there all the same anyway im just gutted i may have to take the engine out again on my k0
