Good Easter thanks. Hope you had a good one too. Was definitely biking weather. Went out after the little service and love that other bikers give a little nod when you pass them on the road!
Anyhow, to business. Only mod I’m aware of is the full black widow stainless steel system straight through from cylinders. Air filter looks OEM (no branding visible) and not ventured to look at the jets yet. Bike was bought in Portsmouth and the exhaust at the same time so perhaps other mods from the outset but nothing i can find in the paperwork and last owner didn’t think so. I did think it was maybe running a little rich when starting as strong smell of petrol, half choke needed together with a twist of throttle (keeping revs low) to start,  but didn’t know if that was normal?CR8’s from you have definitely made an improvement, although not any significant power increase the rideability has improved. Seems to be a little snappier on the throttle and its now idling a little lower when warm. Cold start also slightly improved, but need to turn her over a good few times before she fires. Really want to get the carb off and cleaned, but worried about the clamp. Will get some decent photos posted of the offending rusted clamps tomorrow if it helps. Any advice on removal would be greatly appreciated. Totally don’t want to end up breaking a part that’s hard to replace like the intake manifolds.
I dropped her flat on the right side today (left the disks lock off when pulling out of a parking space and she’s heavy girl, Felt shame!). Nothing major and managed to hold it so it wasn’t a big whack. Bent the brake lever a little, but still well usable. There was a pool of petrol where she landed. Presuming from carbs as it was around that area and it did take much longer to start, after I‘d left it standing for 10 mins. Few questions about this. Would this petrol be from the carb? If it is should it be holding petrol once the engine’s killed? If its running rich is this overfuelling the carb and the reason why its holding petrol? Is it not the carb at all but from somewhere else (the tank as the petrol was sloshing when I dropped it)? Any idea where i can get a second hand lever (only)?
Was going to fudge together a bodged stand with a thick piece of wood and two axle stands under the frame, but the exhaust fouls up that idea, ands probably wasn’t a good idea from the start. Don’t have paddock stands at the moment, so will be investing in a set together with some bobbins from the shop when I get paid at the end of the month. Probably the oil plugs and filler bolts as well.
Compression tester is made by Roadster (?) and was £20 on line, with an additional bike adaptor i had to buy separate as photo. Might be able to speak with a car mechanic (friend of a friend) see if he can compression test or lend me his tester. What would be good/expected compression front and back? Are my readings way off?
Thanks for the advice on bolts. Thought it would leak fluids in some places if I took them all off at the same time, but didn‘t know if I needed to drain oil again. 1 in 1 out approach is great and much easier. Smaller torque wrench on the shopping list now as the one I’ve bought is min 20nm.
