Hello all,
There was a bit of this in my last thread, but probably easier to start another.
pics here for those not familiar with the most recent hair-brained scheme:
http://team-thumper.blogspot.comI've been cleaning up the new motor, putting studs in etc, and wanted a bit of info.
The cases are I believe XTZ. Engine no. 4NN-001891
Can anyone confirm what this is, year etc?? the side cover says MZ, but that really means nothing could be any cover...
I think (as SteveL says) the head and barrel are XT.
Head: 2KF 01
Barrel: 3AJ00 595cm3
Now, I think originally the barrel "nuts" (to the cases) were these silly, ally "male nuts" wuth a hex on them. I dont like the idea of this! And it broke the studs last time with these (as a 690).
I noticed my 620 SRX has normal nuts. I have new studs and nuts to use. Better?? Any scientific (or other!) reason why they're better?? And should I also use washers (phosphor bronze or otherwise?- certainly on the head, but should I re-use these old ones, or should they be new)
(I was delighted to find a new barrel gasket and oversize head gasket, new studs, nuts and headbolts. All good, as they'd be about 50 quid I'd think )
Also, I've always used blue hylomar, including last time on the SRX head, and rocker box. very little, and not a trace of oil, no blown gaskets etc. Its a bit oldschool I know, but I am a luddite, with a strong dislike of elecctric starters and the like! I have used this on every engine I've built, but this is mostly brits admittedly. Never any problems tho, and I've always used it when I take any covers off.
I plan to use it on barrel, head and rockerbox. A problem??
And finally, the stage 4 cam runs VERY close to the head. Will try to post some phootos on the blog site later, but its almost unmeasurable with feelers.... About 2 thou?!! Can the SRX/XT cam bend,flex or move at all? I suppose clearance is clearance, and if it cant thrash about, then it cant hit. But should I remove a little more metal (already had a fair bit off) ? The head has run like this, but I dunno how hard...
Anyway folks, thanks for info, much appreciated!
And I've re-jigged the site a little if you want to click around it. Some more piccies, and a very handsome picture of our very own Boyd Brooks!!
And the "List of the Fabulous", the vast majority of whom kick about on this forum. Thanks a lot guys (inc mav, the most recent member of this brilliant group). Thats the real reason for the site, and the blog, so that you chaps can keep abreast of what is happeneing. Cos now, this is partly YOUR project, not just mine and boyd's! Nice huh?!
Have a look, there's a link on the left hand side.
"Speak" soon,
