dajogejr Posted April 15, 2010 Report Share Posted April 15, 2010 Go spend the 3 to 5 bucks unless you like doing everything twice. No need for yamabond at all...any RTV will work, blue, red, black, hi temp..does not matter. Quote Link to comment Share on other sites More sharing options...
alf44 Posted April 15, 2010 Report Share Posted April 15, 2010 With all of these modquad heads leaking I would think twice before buying one. I cant believe that they said to just silicone it IMO thats fucked up. Aint that what the orings are for? I have had my vitos hemi head for about 6 years now and I've never had a problem. This sounds like this is something that modquad needs to address. Modquad makes the Vitos head. There damn near identical.. Quote Link to comment Share on other sites More sharing options...
AKheathen Posted April 16, 2010 Report Share Posted April 16, 2010 oh, man...i hope that yamabond doesn't gum up in the threads, lol.....i would have used the blue non-hardening rtv...just aboiut the best for many coolant system parts Quote Link to comment Share on other sites More sharing options...
overrevtricky Posted April 16, 2010 Author Report Share Posted April 16, 2010 There is a very easy fix for this. Get new copper...or I prefer brass washers. Get Acorn nuts. Put the washers on, put a dab of silicone on the threads of the acorn nuts and torque them down. I promise you no issues. The center studs are good for leaking. With brass washers and RTV'd acorn nuts they won't. Period. The Chariot head I have came with heavy duty Chrome Acorn nuts. Not just tough, but very good looking on the bike too. Filled it up today with coolant, had the stock nuts with yamabond on them, no dice. Picked up some acorn nuts and Permatex non-drying gasket making material, made to seal threaded connections. Filled it up with coolant again, works like a charm! Thanks alot for the help guys. On a side note, dont buy this head! lol Modquad really needs to take this one back to the drawing board!!

AKheathen Posted April 16, 2010 Report Share Posted April 16, 2010 i bet you could fiv it yourself by running a 7/8 drill bit, or reamer with 45-60 degree in the holes on the bottom, and put the 10 o-rings in there Quote Link to comment Share on other sites More sharing options...
alf44 Posted April 16, 2010 Report Share Posted April 16, 2010 I love mine and have had no problems. sell several of them every week. The funny thing is when there compared to the Vitos head. lol. There the same head. I like the one piece design, no need to change head studs and the fact that theres 33% more coolant capacity. If you need to use a little somthin extra to seal it, so be it. Big deal. Your still in it for less than a new pro design. Once you Buy the orings, head studs and domes your in it over $300. Far more than a complete modquad setup, with domes. Oh ya, just my .02. lol. Quote Link to comment Share on other sites More sharing options...

b.rich108 Posted January 9, 2014 Report Share Posted January 9, 2014 I know I am digging up an old thread, but do the modquad o ring kits come with the big gasket that goes around the whole head, or is this not needed? It does not look like it comes with it in the pictures but I don't understand why it wouldn't. Quote Link to comment Share on other sites More sharing options...

b.rich108 Posted January 16, 2014 Report Share Posted January 16, 2014 Just to clarify....the "one big o-ring" is actually 2 O-rings. The mod quad head doesn't use 1 o-ring that goes around the whole head. That's why I asked a "4th" time in a thread that head people that ran modquad heads Quote Link to comment Share on other sites More sharing options...
