Questions:
K8 - Where does the breather tank oil drain run? This is the bolt-up type catch pot with the u-bend drain hose.
K7 - Where does the points plate wiring run, is it along the frame or under the engine by the neutral switch wiring? If its along the frame anyone know the clip part number (want to use the correct part, not tie wrap).

Anyone know the length of the tacho cable for the 750k7? I was supplied with a new one by the previous owner but it seems to be 1 to 2 inches too long. DS does not have one in stock at the moment for them to measure.

Any one know if there should be a plug in the gallery shown on the photo (I have drawn a line to it). Its at the bottom of the gear shift linkage cover and its normally covered by the gasket and cover. The microfiche shows a plug 91256-096-651 but I found this was for the end of the starter reduction gear shaft. Is it the same part for this gallery? None of my strip down photos shows it and the manuals I have aren't clear or do not cover the area.

I am having problems getting the 2-3 points on the 750 to adjust. They need to move anti-clockwise (about 10-15 degrees) further than the adjustment allows so obviously something is wrong. Points 1-4 set up OK. The points plate is new so I thought it would be a quick install but I have been at this for ages!! Everything looks OK, I am now wondering if someone replaced the advance/retard mech' as the locating pin is a little small for the crankshaft hole and does not give a positive fit - is there any way of identifying the correct one?.
Before I stripped the bike I found the old plate had the 2-3 points on full anticlockwise adjustment as well.
Any ideas?

Just thought I'd share this with you.
Changed the exhaust valve guides today on the K7. New fan oven set to 170 deg C (thanks Marg). Head well supported and soaked for at least 40 minutes at that temperature. Used stepped drifts to get them out and to put them in, the stepped drift for putting them in went all the way inside the guide to support it. Head put back in oven for each guide operation. Really tight to get them out but not so bad putting them in. All went well until this happened! Change in note from the drift, pulled the drift out and the top of the guide fell off!
I have changed a number of guides on different engines and never a problem until now.

Has anyone over here in the UK had any experience of using Edelbrock "Gasgacinch" gasket sealer on our 4 cylinder head gaskets when fitting them? Cycle-X use it on their rebuilds and I've been told air-cooled VW owners use it as well. I've got a tin of it and it looks almost like Evostik in texture.

Anyone know what the stock needle position is on the 1977 750 K7 (UK model) to give me a base setting? The bike is being completely rebuilt with new stock exhaust and rebuilt engine. I am now overhauling the carbs and it's obvious that they have been apart in the past but I don't know if the person messed with the needle position. The clips are in the top (leanest position) groove on all carbs. My Honda (genuine) manual has a diagram showing them in the middle position but makes no mention of the position in the write-up. As I have found inaccuracies in the manual before I don't really trust it!!

Anyone know what the difference is between the PD41A-A and PD41A-B carbs is? I was going to use genuine honda parts for the rebuild on my 41A-A carbs but some parts aren't available (like needle jet assemblies) but they are available for the 41A-B. Has anyone used the 'B' parts in the 'A' carbs?

Can someone please let me know what the cover of the riders handbook (the small booklet that goes under the set) looks like for the 1977 UK spec K7 (colour and text). I need to find one in good condition but have only seen ones on the USA ebay site and am not sure if those marked '77 are for the K7 and if so are the US ones different to the UK ones? I have contacted a couple of sellers on the US site and they have simply said that since the maintenance on all the 750's is the same their booklets will do!
You can email me a photo if you can (email on details page) or if you have a good spare one let me know.
Had 2 ebay bargains last week! A genuine Triumph Workshop manual for the Hinckley Bonneville at

Just had my 750K7 tank, side panels and chainguard back from the painter that I use. The shine and depth of colour is superb. Mick painted on the stripes as he does not like using decals. I will post some pics up on here when I can get to do some good photos, its very difficult with shiny black! His contact details are: Mick Neill, Custom Paint Studio, 01922 497303.

Anyone tried and had success in removing the transparent reservoir off the k7 master cylinder? I want to remove it to have the casting refinished but it will not budge! I assume its threaded but is it left hand or right hand?). Its not available as a spare so do not want to damage it.

Question for those with experience of 750K7 (and F2?). The nearly new front ( engine) sprocket on my bike has a small amount of end float when the bolt is tightened which allows the sprocket to wobble slightly. Is this normal on these bikes or is it supposed to be rigidly fixed? I have seen in print that some other makes have this feature but have not come across it before. I thought that this would increase the wear on the drive splines.
Secondly, does the shouldered side of the sprocket face out or towards the engine?

Just blasted one of the cylinder head oil control jets into space! (well, into the neighbours garden). Has anyone got one rolling about anywhere? Part number is 12283-300-010 and is off my 750K7. It's the one that feeds the oil to the cam and sits in the top of the head under the cam block.

Just bought 4 sets of OEM rings from Dave Silvers. They are NPR (Nippon Piston Ring Co). In each set there is ring that has a bright edge and a ring that looks to be plain cast iron. The bright edge one has a "1N" mark stamped on it and feels slightly rounded (no sharp edges). Am I correct in thinking the bright edge one is the No1 (compression) ring and should be installed with the marking facing the top, the plain ring would then be the No.2 ring?
Anyone had any experience? I can't find any info on the NPR site and am waiting a reply from D.S.

Now in the position to get the paintwork done on this project! Can anyone tell me if the thin red stripe on the tank stripes for a black K7 is bright (Post Office) red? the stripe on mine is a pinky red but I think this must have faded. I am not using decals, the painter who I use (a superb custom painter) won't touch them !
